WINDOW.

sPEcrFIcATroN forming part of Lea-ers Patent No. 652,553, dated June 26,1900.

Application filed February 3, 1900. Serial No. 3,792. (No model.)

To f1/ZZ whom t may con/cern.-

Be it known that I, WILLIAM D. VATSON, a citizen of the United States,residing at Chicago, in the county of Cook, in the State of Illinois,(Whose post-oiiice address is No. 229 Walnut street, Chicago, Illinois,)have invented certain new and useful Improvements in Vindows, of whichthe following is a speciiication.

My invention relates more particularly to swinging windows and towindows of sheetmetal construction made in accordance with municipalfire-protection regulations; but in some of its features the inventionis applicable as Well to sliding windows or to .windows made of woodinstead of metal.

Aprincipal object of the invention is to provide improvedweather-excluding devices to be applied between the sides of the windowframe and sash, as well as to provide a generally-improved constructionin structures of this character; Vand the invention consists in thematters hereinafter set forth, and particularly pointed out in theappended claims,when considered in connection with the accompanyingdrawings, which illustrate a windowframe and swinging sash constructedof metal and embodying my improvements in one form.

In said drawings, Figure l is a horizontal section taken through thewindow sash and casing. Fig. 2 is a transverse vertical section thereof.Fig. 3 is an enlarged horizontal sectional detail showin g the sash asswung slightly out of its closed position and showing the weather-tubesforced back accordingly, and Fig. 4 is a vertical sectional detail takenon a plane through the weather-tubes and side of the window-casing.

In said drawings, l designates the windowsash, within which the glass Gis secured in any suitable manner, and 2 is the windowcasing, which isbuilt into the aperture in the wall of the building to receive the sash.The sash-frame is herein shown as of Atubular construction, with aninwardly-projecting channel 4L extending entirely around the frame andforming a condensation-gutter, at the bottom of which one or moreapertures 5 are desirably provided to permit the escape of any moisturecollecting therein. Pivotbolts 6 to pivotally support the sash are shownas passing through this channel portion 4 of the sash and through theadjacent sides of the window-casing at points which are considerably outof the plane ofthe center of gravity of the sash when closed, and theweight of the sash consequently always tends to swing it closed, thisself-closing tendency being increased by locating the pivots 6 somewhatabove theiniddle of the sash. Suitable chains or other contrivances willthen be provided for holding the sash open when desired, but are notherein illustrated, as they have no particular bearing on the case inhand.

To exclude the weather at the joints between the sides of the swingingsash and the casing, spring-pressed weather-tubes 7 are provided invertical grooves or recesses 8 in the sides of said casing. These tubesproject, when the sash is closed, into vertical grooves 9, formed intheadjacent side surfaces of the sash, and iit therein so closely as toeffectually exclude the weather. When the sash is swung on its pivots 6,the weather-tubes are forced back into the recesses 8, as shown in Fig.3, by the wedging action of the sash on the curved surfaces of the tubesas the sash swings out of line therewith, and the fact that the pivots 6are considerably to one side of the tubes 7 renders such wedging actionon the latter more effective and gradual. When the sash is once morereturned to its closed position, the tubes instantly spring forwardagain into the grooves and seal the openings between the sides of thesash and the casing. are not fastened within their recesses 8,- but aresimply loosely placed therein before the Y sash is mounted within thecasing, and the tube-springslO are herein shown as made in the form ofbow-shaped plate-springs that are removably secured to the tubes byscrews 11. This renders it a very simple matter to remove the tubesand'replace the springs in case any failure should occur in the latter.It will, however, be understood that said As herein shown, the tubes '7springs may be otherwise formed or provided,

if desired. It willalso be understoodv that while the hollowconstruction of the weathertubes is preferred on account of theirgreater lightness and economy solid or other vthan tubular bars may beemployed to the same end, and various otherchanges may be made in thedetails of the construction described Without involving any materialdeparture from the broad invention claimed.

I claim as my inventionl 1. The combination, with a Window-easing andinclosed sash, of pivots extending between the sides of the casing andsash to pivotally support the latter, and interposed spring-pressed barsseated in grooves extending along said pivotally-connected sides aboveand below the pivots thereof, substantally as described.

2. The combination, With a Window-casing,

of a sash mounted therein upon horizontalpivots extending between thesides of the sash and casing, said pivotally-oonnected sides beingprovided with vertical grooves extending above and below the pivotsthereof, and interposed spring-pressed bars removably seated in thegrooves in the casing and yieldingly engaging the grooves in the sashwhen the latter is eiosed but adapted to be forced back and extendangularly acrossthe sash when the latter is open, substantially asdescribed.

' 3. The combination, With a Window-casing and a sash pivotally mountedtherein, of inin the one and fitting into coaoting grooves in the otherWhen the sash is closed, the sashpivots being offset from the plane ofsaid bars, substantially as described.

4.. The combination, With the Window-case ing 2, provided With therecesses 8, of the tuvbular sash l, provided with the surroundingchannel 4, pivot 6 extending through said 'channel into the casing,grooves 9 in the lateral faces of the tubular sash removed from tubes-7seated within the recesses 8 and nor- 'mally projecting into the grooves9, substantialiy as described.

In testimony that I claim the foregoing as ymy invention I affix mysignature, in presence of two subscribing witnesses, this 1st day ofFebruary, A. D. 1900.
